7.5.1.1 Triggers
All inputs configured as triggers are linked by AND. If several inputs are being used as triggers, a
high signal must be present on all inputs in order to generate a trigger signal. The polarity for
each signal can be set separately via the inverting inputs. The camera must be set to "external
iggering" to trigger image capture by the trigger signal.
